In the use of dye-books and other niachines of the class in which there is a liquid vat of wood with'upstanding uprights secured to opposite side walls of the vat and 6 serving to carry a reel rotating on a horizontal axis so as to convey the goods to be dyed or otherwise treated through the liquid in the vat much trouble is experienced by the sides of the vat warping and thereby causing the' uprights to assume distorted positions and consequently, through dison I alineinent of the bearings for the reel, set ting up so considerable binding thereof in the bearings that it requires a wasteful expenditure of power to drive the reel. The object of this invention is to provide a machineof this class in which the warping of the wooden vat and consequent shifting of the uprights toydistorted positions will result in no binding of. the reel in its bearings. In carrying out this object, instead of employing a single shaft forthe reel according to custom or adopting any equivalent construction in which the terminals of the axial part of the reel are in fixed alinement with each other with one equipped with a gear or other means by which to transmit rotating motion to the reel, I employ the construction thus generally stated, to wit: The reel, according to my invention, has rigidly alined horizontal axial portions projecting laterally therefrom and these are journaled in bearing means in the respective uprights each adapted to permit the corresponding axial portion to assume dif ferent angular relations to the adjoining upright (as when the latter is made to assume a distorted position) and one being capable of shifting lengthwise thereof in its bearing means; and for the driving of the reel there is preferably a rotary driving member, as a shaft, axially opposed to the other axial portion and having a universal coupling connection therewith and being journaled on a fixed axis in the other upright. By this construction if warping occurs and consequently the uprights assume distorted positions the reel continues nevertheless to rotate with no greater friction or other resistance than in the initial condition of the machine.

Fig. 1 of the accompanying drawing is a view showing partly in elevation but mainly in. vertical. section substantially new trally of the reel a dye-bech constructed according to this invention; and

Fig. 2 shows a detail, in section, of one of the bearings for the reel.

The sides of the wooden vat 1 are indicated at 2. Upstanding from and rigidly secured to these. are two uprights 3 3 which I shall describemore in detail hereafter.

i is the reel and 5 its laterally extending portions, bei'ng in the present case the ends of the shaft 6. The upright 3 may be a metal casting and follow the usual construction excepting that it is provided with a cavity 7 for what is known as a self-alining bearing here consisting of a double-grooved ball-race 8 on the shaft .6, a ball-race 9 fixed in the. cavity by a removable cap '10, and

balls'll; the race surface, of the part 9 is concave as best shown in Fig. 2 whose arc of concavityis struck around a center in the axial line of the shaft, (the object'being to permit the shaft to assume various angular relations tothe upright), and the part 8 is capable of slippage on the shaft lengthwise thereof for a reason to appear.

The upright 3 is a metal casting departing from the usual form in that it has a major housing 11 at the top provided at its inner side with a minor housing 12. The inner side of the minor housing is formed with a cavity 13 for a self-alining bearing generally denoted by 14; and in all respects the same as the self-alining bearing already described, this hearing 14 being confined in the cavity by a cap 15 removably secured to the inner side of the minor housing; in this case, however, the inner ball race of the bearing need not be capable of slippage on the shaft and is in fact confined between a shoulder 16 on the shaft and a disk 21 secured thereon and to be described.

In view of the foregoing it will be seen that the reel can rotate without binding or other resistance althoughthe uprights may undergo distortion from their original relation to each other and the shaft 6, as by either or both assuming any oblique relation to the shaft or by their spacing from each other being altered; if the change manifests itself by an oblique position of either upright binding is avoided because the members of the self-alining binding affected can assume tilted relation to each other and still function in the normal way, without trie tion, and if a change in the spacing of the uprights ensues lengthwise binding of the shaft in its bearings is avoided because it may slip in the bearing means at one end thereof.

The reel might be rotated in any way, but it is desired to obtain a driving of the reel not tending to skew it in its bearings, where fore I prefer to drive it by a rotary driving member axially opposed to its shaft 6. This member rotates on a fixed axis in bearings in one of the uprights and it is connected with the shaft by a universal coupling connection thus: In bearing 17 and 18 in major housing 11 is journaled said driving member 19, here a shaft; these bearings are ball bearings and so confine the shaft against lengthwise movement. Said memher and shaft 6 are axially opposed and they have keyed thereon, within the minor housing, spaced disks 20 and 21; disk 21 has lateral pins 21 and disk 20 has holes 20 loose- 1y receiving the pins, so that they form a universal coupling connection between the shafts (i and 19.

It is not material how member 19 is itself driven, but I show a gear 22 whose hub 22 is revoluble on the shaft at 22 and meshing with a pinion 23 fixed to a gear 24 revoluble in suitable hearings in upright 3 and in turn meshing with a pinion 25 on the shaft of an electric motor 26. The hub of the gear 22 is interposed between a collar 27 fixed on shaft 19 and a clutch member 28 which is adapted to cooperate with the'hub of said gear 22 to form a clutch when the clutch member 28 is properly manipulated by manual controlling means 29.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is:

1. In combination, the vat, uprights rigidly securcd to and upstanding from opposite sides of the vat, a reel. having rigidly alined horizontal axial portions projecting laterally therefrom, the uprights having bearing means above the vat for the respective axial portions each adapted to permit the corresponding axial portion to assume different angular relations to the adjoining upright and one axial portion being capable of shifting lengthwise thereof in its bearing means, and means to rotate the reel.

2. In combination, the vat, uprights rigidly secured to and upstanding from opposite sides of the vat, a reel having rigidly alined horizontal axial portions projecting laterally therefrom, the uprights having bearing means above the vat for the respective axial portions each adapted to permit the corresponding axial portion to assume different angular relations to the adjoining upright and one axial portion being capable of shifting lengthwise thereof in its bearing means, and a rotary driving member axially opposed to one of the axial portions and having a universal coupling connection therewith and journaled on a fixed axis in the other upright.

In testimony whereof I affix my signature.
